OF BAYONNE, NEVJ JERSEY, ASSIGNO'R TO AMERICAN CAR AIil'D FOUNDRY COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEYV JERSEY.

COMBINED GAP AND ROD VJRENCH.

Applicationfiled June 15, 1922.

T all whom it may concern Be it known that I, CLYDE H. FoLMsnnn, residingat Bayonne, Hudson County, State of New Jersey, and being a citizen of the United States, have invented certain new and useful Improvements in a Combined (lap and Rod Wrench, of which the following is full, clear, and exact description, such as will enable others skilled in the art to which it appertains to makeand to use the same, reference being had to the accompanying drawings which. illustrate the preferred form' of the invention. though it is to be understood that the invention is not lini-.

ited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings:

Fig. l is a central vertical section of a car tank dome with my invention applied thereto;

Fig. 2 is a top plan view of the structure shown in Fig. 1; and

Fig. 3 is a view, partly in section, showing the cap removed and used to operate the discharge valve operating rod.

It is the object of my invention to provide an improved covering means for valve operating rods and air inlet passages for car tanks of the type shown in the application of John J. McBride, Serial No. 568,509, filed June 15, 1922, which will serve as an operating means for the discharge valve rod.

With these and other objects in view, my invention comprises a flanged member 1 secured to the dome head 2 of a car tank by rivets 3 passing throughvthe flange 4c of the member 1, the flange 4c surrounding an opening 5, in the dome head 2. While I have shown my device as applied to a tank having a layer of heat insulating material 6 and an outer protecting sheath 7, it is to be understood that my invention may be used with uninsulated tanks. The member 1 comprises a base portion 8 surrounded by the flange 1 and having the projecting walls 9 and 10, the wall 10 being of less height than the wall 9 and merging with the wall 9 for part of its length. The walls 9 and 10 and base 8 define a chamber 30 which is in open communication with an irregular passage 11 and a chamber 12, the passage 11 and chamber 12 leading to a threaded opening 13 and Serial No. 568,664.

an opening 14, respectively, in the base 8. 111 the threaded opening 13 is mounted the casing 15 of an auton'iatically operating air inlet valve. The air inlet valve may be of any suitable construction, the one shown comprising a valve 16 held to its seat in. the separating wall 1'? of the valve casing 15 by levers 18 which are fulcrumed on the casing 15 and carry an annular weight 19 which surrounds the casing 15. The valve is guided in its movements by a stem 20 which engages with the guides 21 formed integral with the casing 15. Projecting through the opening let is a discharge valve operating rod 22 which extends through chambers 12 and and is surrounded in chamber 12 by packing 23 held in position by packing nut 24. he upper portion of the wall 9 is threaded to receive a cap 25 having a thread ed portion 26 adapted to fitover the rod 22 and engage with the threaded portion of the wall 9 thus closing the passage to the air inlet valve and forming a protection for the discharge valve operating rod 22. The cap 25 is also provided with operating arms 27 and a socket 28 adapted to fit the squared end 29 of the rod 22 to operate the discharge valve (not shown).

It will be noted that the cap 25 when in the position shown in Figs. 1 and 2 closes the inlet passage 11 leading to the air inlet valve and protects the discharge valve operating rod from tampering and that in the position shown in Fig. 3, the inlet passage 11 is open and the cap 25 forms a wrench for turning the rod 22 to operate the discharge valve of the tank.

That I claim is:

1. As a new article of manufacture, an integral cast cap having a closure portion, a socket portion adapted to serve as a wrench and means to operate said cap when used as a wrench.

2. As a new article of manufacture, a cap having a closure portion, a portion adapted to serve as a. wrench and operating arms adapted to operate said cap as a closure and as a wrench.

3. As a new article of manufacture, an integral cast cap having a closure portion adapted to serve as a wrench, a socket portion and arms to operate said cap when used as a wrench.

4. As a new article of manufacture a cap having a socket portion adapted to serve as a wrench and means to operate said cap when used as a wrench;

5. As a new article of manufacturea cap having a socket portion formed integral 5 therewith and adapted to serve as a. wrench and operating means for said cap when used as a wrench.

6. As a new article of manufacture, a cap having operating arms and a; socket-portion 10 formed integral therewith, said socket porwrench.

tionh'ein'gndaptd to servees awrenchand sa1d=operat1ng means being adapted to operate-saidcap when used as a closure and as a Inwitness-whereoflhave hereunto set 15 my hand in the presence of two witnesses. CLYDE H. FOLMSBEE.
